SHUTTER-FASTENER.

SPECIFICATION forming part of Letters Patent No. 379,695, dated March 20, 1888.

Application filed November 19,1887.

To all whom, it may concern.-

Be it known that I, PAUL O. GUERIN, a citizen of the United States, residing at New Orleans, parish of Orleans, State of Louisiana, have invented a new and useful Shutter-Fastener, of which the following is aspecification.

This invention has relation to improvements in locks for window blinds or shutters, and it has for its object,in addition to securely locking the blinds, means whereby the lock or fastening may be manipulated and the blinds opened by a person outside the house.

The invention will be fully understood from thefollowingdescription and claim,when taken in connection with the annexed drawings, in which- 7 Figure l is a view ofa portion of abuilding, showing two windows, one with the blinds open and the other with them closed, having my improvements applied. Fig. 2 is a perspective View of a portion of a window-blind, showing myiniprovements and a lever or spanner for manipulating the same; and Fig. 3 is a view of a portion ofablind,showing my improvements in an operative position and the lever or spanner applied.

Referring by letter to the said drawings, K indicates window-blinds, which may be ofany ordinary construction and properly hingedto the window-frame. Journaled in one of the blinds at a suitable point isa horizontal shaft, G, which extends a snfficient distance on the inner side of the blind to receive a winding cord or chain, 0, one end of which is secured thereto. This shaft G has its bearing in a socket, H, and its outer end is enlarged or headed, as shown at A, whereby the same may be properly retained in positiou,and the headed Serial No. 255,666. (No model.)

in a vertical line below the shaft G. This post D is fixed in the blind and is slotted, as shown, to receive a key, B. This key is attached to the lower end of a chain and is drawn out of the slot of said post by turning the shaft to wind the chain thereon.

I indicates a lock-bar which may be retained across the windowopening in suitablekcepers, as more fully shown in Fig. 1, and is provided with a transverse aperture, a, which is designed to receive the bolt D in the blinds when the latter have been closed.

The spanner J, I have shown is of the form commonly used by firemen, having two points arranged at a suitable distance apart to enter the apertures in the turn-shaft; but it is obvious that a single rectangular aperture may be formed in the said shaft and a key with a corresponding point employed.

In operation it will be seen that when the blinds are closed and the bar I placed in position the post 1) will pass' through the apertn re A therein. The key is then taken hold ofaud placed in the slot of the said post on the inner side of the bar 1. It will thus be seen that the blinds are locked in a closed position. The blinds may be opened from the inside by simply withdrawing the key from the slot of the bolt D, and this operation may be performed on the outside by simply turning the shaft G, so as to wind the key-chain thereon.

Havingdescribed myinvention,whatIclaim 1s- The combination, with a window-blind, ofa slotted post or stud secured thereto, a cross bar adapted to be placed across the opening of a window and having an aperture to receive the said stud, a key adapted to be placed in the slot of the stud, the rotating operating-shaft provided with exterior openings to receive a spanner, and the chain connecting thesaid key with the shaft, substantially as specified.

- PAUL o. GUERIN.
